# SDL_HapticOpenFromJoystick

Open a haptic device for use from a joystick device.

## Header File

Defined in [SDL_haptic.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_haptic.h)

## Syntax

```c
SDL_Haptic* SDL_HapticOpenFromJoystick(SDL_Joystick *
                                       joystick);
```

## Function Parameters

|                                |              |                                                                  |
| ------------------------------ | ------------ | ---------------------------------------------------------------- |
| [SDL_Joystick](SDL_Joystick) * | **joystick** | the [SDL_Joystick](SDL_Joystick) to create a haptic device from. |

## Return Value

([SDL_Haptic](SDL_Haptic) *) Returns a valid haptic device identifier on
success or NULL on failure; call [SDL_GetError](SDL_GetError)() for more
information.

## Remarks

You must still close the haptic device separately. It will not be closed
with the joystick.

When opened from a joystick you should first close the haptic device before
closing the joystick device. If not, on some implementations the haptic
device will also get unallocated and you'll be unable to use force feedback
on that device.

## Version

This function is available since SDL 2.0.0.
